Title:
CONVEYOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/090221
Kind Code:
A1
Abstract:
In order to restrict variation in speed of treadboard rollers (5), turning sections (17) are formed on a tread guide rail (3) and a press-down member (18) is provided at the front stage of a conveyor device. The height and shape of the turning sections (17) and the press-down member (18) are corrected in advance by the amount corresponding to the amount of compression of an elastic member, formed on each treadboad roller (5) about its axis, caused by a pressing force acting between the turning sections (17) and the press-down member (18). By this, variation in speed of treadboards (4) is appropriately restricted to improve riding comfort of the conveyor device. Further, a recess (3aa) is provided in the tradboard guide rail (3) so that the treadboard rollers (5) rolling and moving on the lower surface of the press-down member (18) are avoided from being clasped from below to prevent damage on the treadboard rollers (5), press-down member (18), and treadboard guide rail (3).
